In collaboration with the Bonvent UG and the Robert Krebs GmbH, the Breisach dam was renovated, with Bonvent organizing the nautical side of the project. In cooperation with the Wasser- und Schifffahrtsamt and the Wasserschutzpolizei, a ship with equipment has been made available for this project. The ship was placed in front of the weir with a safety plan. The project is largely completed and all participants have experienced this “new” form (use of a barge) as an excellent alternative to conventional methods.
